Set­ting a mile­stone in the wind ener­gy indus­try

Wind Craft has deve­lo­ped a paten­ted, mobi­le laser clad­ding pro­cess that enables the repair of worn bea­ring seats direct­ly insi­de the nacel­le – wit­hout remo­ving the shaft and wit­hout the need to replace major com­pon­ents.

The Pro­cess

1) Pre­cis­i­on machi­ning

The dama­ged bea­ring seat is pre­cis­e­ly bored and machi­ned

2) Laser clad­ding

Mate­ri­al is being appli­ed.

3) Results of Laser Clad­ding

4) Cus­tom pre­cis­i­on machi­ning

Grind back to the ori­gi­nal tole­rance.

5) Result: Cus­tom Finis­hing

Con­ti­nuous moni­to­ring and qua­li­ty con­trol

Throug­hout the enti­re pro­cess, tem­pe­ra­tu­re and dimen­sio­nal mea­su­re­ments are con­ti­nuous­ly moni­to­red. This ensu­res full res­to­ra­ti­on within spe­ci­fied tole­ran­ces.

Your bene­fits

Mini­mal down­ti­me

On-site repair insi­de the nacel­le dra­sti­cal­ly redu­ces down­ti­me.

Signi­fi­cant cost savings

No major com­po­nent repla­ce­ment requi­red – up to 70 – 90% more cost-effec­ti­ve than repla­ce­ment.

Pre­dic­ta­ble main­ten­an­ce

Fast sche­du­ling and cle­ar­ly defi­ned pro­cess steps ensu­re relia­ble plan­ning.

Inde­pen­dent & sus­tainable pro­cess

Com­pon­ents are reused—this con­ser­ves resour­ces, is sus­tainable, and pro­tects the envi­ron­ment.

Our paten­ted repair tech­no­lo­gy

Our pro­cess enables the pre­cise repair of dama­ged gene­ra­tor shafts and worn bea­ring seats direct­ly at the gene­ra­tor – wit­hout dis­mant­ling major com­pon­ents. Using advan­ced laser clad­ding and pre­cis­i­on finish machi­ning, we relia­bly res­to­re the ori­gi­nal fit and tole­ran­ces.

This tech­no­lo­gy has alre­a­dy been suc­cessful­ly appli­ed in more than 100 units and has pro­ven to be dura­ble, robust, and high­ly effi­ci­ent. The result: signi­fi­cant­ly redu­ced down­ti­me, lower cos­ts, and a sus­tainable exten­si­on of asset life­time.

Thanks to its mobi­le design, the pro­cess can be appli­ed not only in wind tur­bi­nes, but also in mari­ne dri­ve sys­tems and indus­tri­al gene­ra­tors – whe­re­ver major com­po­nent repla­ce­ment is eco­no­mic­al­ly or logi­sti­cal­ly imprac­ti­cal.

Our pro­cess demons­tra­ted through real-world refe­ren­ces

1) Worn bea­ring seat / dama­ged gene­ra­tor shaft

The typi­cal initi­al con­di­ti­on: mate­ri­al wear, scoring, and loss of tole­rance. In this sta­te, safe ope­ra­ti­on is no lon­ger pos­si­ble – this is whe­re our repair pro­cess beg­ins.

2) Finish-machi­ned bea­ring seat – pre­cis­i­on within 0.06mm

Finish machi­ning and mea­su­re­ment of the repai­red bea­ring seat
After wel­ding, the sur­face is pre­cis­e­ly ground back to its ori­gi­nal dimen­si­ons. Mea­su­re­ment con­firms an accu­ra­cy within a few hundredths of a mil­li­met­re.

3) Recon­di­tio­ned bea­ring seat – rea­dy for instal­la­ti­on

Ful­ly res­to­red bea­ring seat with rene­wed fit
The bea­ring seat is ful­ly res­to­red, dimen­sio­nal­ly accu­ra­te, and rea­dy for bea­ring instal­la­ti­on. The result matches ori­gi­nal qua­li­ty – wit­hout repla­cing major com­pon­ents.
